This modular system is suited for reef tanks needing flexible light positioning without crowding the water surface. The anodized aluminum construction offers corrosion resistance in humid aquarium environments, making it durable for long-term reef use. Its compact design helps maintain tank aesthetics while enabling precise light coverage and easy access for feeding and maintenance.
Adjustable 30–36-Inch Glass Mount Kit
This larger suspension system uses glass wall mounting, enabling secure attachment to standard or reef tanks with glass walls. With 30 and 36-inch adjustable lengths, it accommodates a broad range of lighting fixtures including metal halide, T5, and LED units. The system’s vertical bars allow precise height adjustments, which helps optimize PAR distribution over a reef tank. It supports clean lines in the setup, reducing clutter around the tank and maintaining a polished aquascape.
Marine Color 250W 14000K HQI Bulb
This 250W HQI single-ended bulb delivers a 14,000K color temperature, supporting reef fluorescence and natural coral coloration. The E40 base is compatible with many standard HQI fixtures, making installation straightforward for reef enthusiasts. This bulb provides strong daytime-like illumination that helps in showcasing coral polyps while maintaining a balanced spectrum suitable for mixed coral systems. It is ideal for mid-to-high light demand tanks needing robust PAR levels.
Marine Color 400W 20,000K HQI Bulb
For deeper water and high-light reef systems, the 400W HQI bulb offers a high-intensity option with a 20,000K spectrum that enhances blue hue and deep-water aesthetics. The single-ended E40 socket facilitates easy installation and stable connection within compatible fixtures. This bulb is suited for large SPS/LPS tanks where intense lighting is necessary to drive coral growth and vivid coloration, while still delivering color balance for an appealing reef display.
Marine Color 70W 6500K HQI Double Ended Bulb
This 70W double-ended HQI bulb delivers a daylight spectrum ideal for smaller or mixed tanks, offering reliable brightness with a daylight-balanced color temperature. The double-ended R7S-like arrangement ensures stable operation and straightforward installation in compatible fixtures. While less common for high-demand reef setups, it can serve as a supplemental source or for systems prioritizing efficient, daylight-focused lighting.
Marine Color 250W 10000K HQI Bulb
The 10000K double-ended HQI bulb provides a bright daylight spectrum designed to enhance reef tank aesthetics and support photosynthetic processes in corals. The FC2 base ensures a solid connection and compatibility with a wide range of HQI fixtures. This bulb can be a reliable primary daylight source for mid-size reef systems, especially when paired with blue-spectrum supplementation for color pop and shimmer.
Buying Guide: Key Considerations for Metal Halide Reef Lighting
- Tank size and coral load: Larger tanks or high-light corals benefit from 400W or 250W HQI bulbs, while smaller tanks may suffice with 70W or 250W options.
- Spectrum needs: For coral coloration and growth, look for bulbs around 14,000–20,000K for enhanced fluorescence and color rendition; daylight (10,000K) can be complemented with blue actinic supplementation.
- Fixture compatibility: Verify base types (E40, FC2), fixture type (single-ended vs double-ended), and whether your ballast supports HQI operation for safe, efficient performance.
- Heat management: HQI lighting generates substantial heat; ensure proper cooling, reliable fans, and appropriate mounting to avoid overheating.
- Mounting and accessibility: Suspension systems and glass mount brackets help optimize light placement and maintenance access without obstructing tank view.
- Durability and corrosion resistance: Aluminum brackets and quality reflectors are essential in humid aquarium environments to prevent degradation over time.
- Maintenance schedule: Regular bulb replacement based on manufacturer recommendations ensures stable PAR and color accuracy for corals and fish.
- Energy considerations: High-output bulbs consume more electricity; plan power usage and consider timers to regulate photoperiods effectively for coral health.
